To all whom it may/'concern' Be 4it known'that I, JAMES H. PEARsoN, a

specification. l

This invention relates to washing machines of that type in which theclothes are beaten by a pounder in a tub or other receptacle, and itsobject is to provide a machine of this kind with improved means foroperating the pounder,` and also to impart to the pounder an alternatingrotary 1novement i so that it will also rub the clothes.

Another object of the invention is to pro.- vide means whereby thecontents of the tub are thoroughly agitated, and also to inject airthereinto, which, together with the rubbing action of the pounderheretofore mentioned, serves to greatly facilitate the washin operation.j'

lith the foregoing objects in view, the invention consists in a novelconstruction and arrangement of parts, to be hereinafter j described andclaimed, reference being had to the drawing heretoutnnexed, in whichFigure 1 is an.` elevation of the apparatus, artly broken away, theclothes receptacle lieing shown in section. Fig 2 isa top plan. view.Fig. 3 is a fragmentagy elevation of a modication.

In the drawing, 5 denotes a waslr-J'roiher,

tub or other suitable receptacle, in which thc clothes to be washed areplaced. Across the to of this receptacle is placed a bar (i, on w ichthe operating mechanism is supported. The bar 6 extends at one end*under one of the handles 7 of the rece tacle, and at its opposite end itcarries a s iding latch 8, which 1s passed through the other handle!) ofthe: rece tacle, whereby the bar is securely held in p ace,` and, at thesame time, is readily removable from the receptacle, so that the clothesmay be placed thereinto, and ref moved. From,the bar 6 rises a standard10, to which is fulcrumed, at 11, an operating lever 12, havinV at eachend -a grip or handle portion 13.- T is lever is o erativelyconpounders, of which two are em' ployed, they being connected to thelever on opposite sides of the fulcrurn, by reason of which one of thepounders will be ascending when the other is descending, and vice versa,'lhe construction ofl the pounders is iden Appliaaifm med January k14,1909. seria1-No.472,se1.

`tical, so that a description of one will sufficel The pounders are.indicated by the reference numeral 14. They are dish-shaped, -the-ydished surface being the working face, and said surface is formed with aplurality of protuberances 15, whichl are for a purpose to bepresently-described. 4The pounder is carried )y a stem 16, which is madehollow and provided with an air inlet 17.` The stem worksin an openingvin lthe bar 6 and extendsl through a central opening in the pounder,and its projecting end is screw-threaded, as indicated at 18, and alsoformed with a seat for a ball valve 19, which works in a cage 20,screwed on said threaded end of the stem a ainst the working face of thepounder. Tie back of the pounder is formed with a groove 21, in whichlits a pin 22, which eX,-v

tends transversely through the stem 16. The cage and pin securely fastenthe pounder on the stem, and the groove in which the pin fits preventsrotation of the pounder on the stem.

In the opposite end of the stem is fitted and secu red a shankv 23,which projects from said'eild of the stem and has its projectingl endVformed with a head 24, which works in a socket 25, n iade in the lever12, whereby'a flexible connection with the lever is. had, and the steinis free to' rotate. The head 24 is `retained in the socket 25 by a plate26, fitting over the outer endthereof and having an opening to receivethe shank 23. The socket is formed with a reduced portion 27, whichextends through to the opposite sideLof the lever and receives a s ring28, which bears on the head 24, and is for the purpose` 0f preventinglost motion. Over this reduced ortion-of the socket is placed a plate29, w ich closes the same, and against which one end of the springbears, the other end thereof engaging the head 24, as already stated.4The plate 29 is bolted or otherwise secured to the lever 12.

'.lhe stem 16 carries a laterally projecting arm 30, to the outer end ofwhich is connectj ed one end of a link 3 1, the other -end of which linkis pivoted at 32 to the standard 10. The 'oint between the arm and thelink is a flexile one, a ball and socket joint, 33, being shown.Inasmuch as thevlink is pivoted to a fixed support,r it will be 'seenthat whenthe lever 12.,` is operated to reciprocate thestem 16,the/latter, fby reason of the connection of Patented JunevvS, 1909. 'p

alternating rotary movement, thereby giv- -ing the pounders' also arubbing action,

which greatly facilitates the washing operation. The protuberances 15are for the purpose of increasing the rubbing action of the pounders.The rotation of the pounders also serves to agitate the water,which alsoincreases the cleansing action. By Vmaking the stem hollow and providingthe same with an air inlet, and also a valve, it will be seen that airis injected into the con-tents of the receptacle Awhen the pounder is inoperation,- and there is no suction to oppose the upstroke ofthepounder. On the bar 6 are mounted rods 34, which extend loosely throughopenings 35 in the lever 12, and around said rods, between the lever andthe bar, are coiled springs 36, said rods and springs being locatedonopposite sides of the fulcrum 11 of the lever. These springs serve toprevent lost motion, and also assist to check and start the movementofthe l pou nders In themodiied form of apparatusshown 1 in Fig. 3 ofthe drawing, a single pounder is i employed, which operates, and isconstructed l in the same manner as the ones already described.

lVliat is claimed is e* In a washing machine, a pounder, a steincarrying the same, a lever operatively connecting the stein, theconnection being such i as to permit rotation of the stem, a laterally iprojecting arm on the stem, a fixed support,

and a link pivoted at one end to said support, and connected at theother end to 'the arm, said connection being by' means of a ilexiblojoint.

In testimony that I claim the foregoing as in the presence of twowitnesses.
